Specification of Letters Patent.

Application filed June 16, 1913. Serial No. 773,972.

To (ZZZ 107mm it may concern:

Be it known that I, LEWIS R. VVr-rnnnnn, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Machine-Tool, of which thefollowing is a specification.

My invention relates to machine-tools wherein universal features aresought, and the objects of my improvement are to provide a mechanism ofportable and convenient size upon which castings and bar stock can beturned, milled, drilled, threaded, knurled, faced, bored, etc., withoutrecourse to the customary and various machine-tools known to the tradeas lathes, milling machines, shapers, drill-presses, etc, at presentrequisite to mechanical operations. By rea son of the requirement ofthese various and expensive machines it is found inexpedient to equipthe laboratory, garage, etc, for machine work, even when it would bemost desirable that such work should not be performed elsewhere.

This invention primarily aims to provide the necessary elements of atool for machine work in such novel form and correlation of parts aswill readily adapt the tool to a great variety of work.

The invention aims to provide a lathe-bed of novel form having onesection extended into an upright column, upon which is placed aheadstock, which, while normally in alinement with a tailstock as in alathe, may be adjusted vertically by a lead-screw or other means; andalso to provide means whereby the spindle of said headstock may beswiveled in a vertical plane, and further, to make such adjustmentswithout interference with the driving mechanism of said spindle, and insuch manner and in such combination with the other component parts ofthe machine as to make the tool equally efficient upon the differentclasses of machine-work.

I attain these objects by the mechanism illustrated in the accompanyingdrawing, in which- Figure 1. is a perspective of the entire machine, andFig. 2. is a sectional view of the head or spindle section showing theswiveling member turned in a perpendicular direction, as well as thedriving members of the spindle.

Like numbers refer to like parts through out the two views.

A bed casting (1) having planed ways on the upper surface serves as asupport and guide for the carriage members (2 and 3) as well as for thetailstock (27). This carriage section is composed of the saddle casting(2) and the slotted table (8), the latter having a transverse motion inthe saddle and the combined functions of holding either a tool-post andstationary tool or clamped work such as castings which may be bolted toits upper surface. A column section (4) is cast integrally with, orbolted rigidly to the bed (1) and serves as a support and guide to theheadstock castings (5 and 6),

the latter carrying the live spindle (7). This spindle is driven fromthe rear by the cone pulley (8), the universal joint (9), the shaft (10)keyed to same by a feather key to allow a limited telescopic motion, theuniversal joint (11 Fig. 2) and the bevel gears (12 and 13 Fig. 2.)respectively.

Of the elements which make up the headstock, one, (5), is gibbed to theslide of the upright section of the bed, and may be raised or loweredupon said section 1) by the screw (14) the nut (15) and the handle (16)or by other suitable means. The other member (6) is machined to fit overthe casting aforementioned in such a way as to allow itself to beadjusted to any angle in the vertical plane. Such angle is obtainedaccurately by the graduation marks inscribed upon the casting (5) asshown at 17, and such angle may be retained by the clamping screw 18. Anout-board bearing arm 19, passed through a bearing in the casting 6 ofthe headstock may be clamped rigidly to same, and at a desired distancefrom same, by the clamping screw 20. A train of change-gears consistingof a pinion 21 on the spindle, an idler 22 on the stud 23 held in theslotted link 24, and a gear 25 on the horizontal lead-screw 26, have thefunction of driving the table or carriage in the required relation tothe revolution of the spindle, when the head carrying said spindle isadjusted into alinement with the tailstock, all as customary in regularlathe practice. These parts are many of them of common and familiarconstruction, but their combination, arrangement and juxtaposition forma novel tool of wide scope in machine work, allowing operations, forwhich many different machines have formerly been necessary, to be doneon one tool, acquiring thereby a machine of wide commercial value andgreat practical utility.

In the practical use of the machine for milling, work bolted to the Tslots of the table 3 in the usual manner may be fed under a rotarycutter mounted upon an arbor (not shown) carried by the spindle. Theouter end of this arbor may be supported if necessary by the arm 19. Ifsuch work be of a nature to require an end mill, the spindle maybeswiveled to a perpendicular posi tion as shown at Fig. 2 and the tableand work fed underneath the end mill in the required directions. If thework should be a gear, it may be mountel on a circular table (not shown)and bolted to the regular table and indexed by: the usual worm gearmechanism, while theformed cutter mills the desired number of teeth inthe periphery of the blank. In a similar manner, other forms of cutterssuch as slitting saws, emery wheels, etc, can be placed upon the arborin any of its positions and the work fed to them."

In' the practical use of the machine for drilling, the head section isturned to a vertical position as shown at 2 and the work laid or clampedto the table underneath. The spindle is then fed'downward by means ofthe lever 28, thus giving the sensitive action necessary to lightdrilling. In this position a tool may be held in the stationary spindleto handily accomplish small key-seating jobs.

Copies of this patent may be obtained for In the practical use of themachine for lathe work, a chuck may be screwed upon the nose of thespindle and the work held therein, or the work may be held betweencenters, the head having been dropped to a level where it is in properalinement with the tailstock. In either case. the work is then rotatedby the spindle and acted upon by the stationary tool held on the table,thereby accomplishing any ofthe operations of turning, facing, threadingetc.

lVhile the elements herein shown are well adapted to serve the purposesset forth, it is obvious that minor changes may be made in theproportions, shape, and arrangements of the several parts withoutdeparting from the spirit and scope of the invention as defined inthe'appended claim.

Having fully described my invention, I claim,

In a machine-tool, the combination of a lathe-bed as described, acarriage, a tailstock, a vertically adjustable headstock composed of twomain members, :the one swiveling upon the other, a graduated dial uponone of said headstockmembers, and a spindle driven from the rear bymeans of bevel gears, universal-joints and telescopic shaft, saiddriving members extending throughthe center of the upright section ofthe lathe-bed.

In testimony whereof I ailix my. signature in the presence of twowitnesses.
